The 4-4-9 Method? ›

4-4-9. In the U.S., most manufacturers use the 4-4-9 method, which assumes that each gram of protein contributes 4 Calories to the caloric total, each gram of carbohydrates contributes 4 Calories, and each gram of fat contributes 9 Calories.

We use the 4/4/9 rule to calculate the number of calories that are represented by your daily macro targets. For example, if your daily macro targets are 200g carbs, 120g protein, and 50g fat, your daily calorie target would be: (200 x 4) + (120 x 4) + (50 x 9) = 1,730 calories.

This popular method of estimating calories assumes that one gram of protein contains 4 calories, that one gram of carbohydrate contains 4 calories, and that one gram of fat contains 9 calories. In beverages or foods containing alcohol, it is assumed that each gram of alcohol provides 7 calories.

The Atwater general factor system includes energy values of 4 kcal per gram (kcal/g) (17 kJ/g) for protein, 4 kcal/g for carbohydrates and 9 kcal/g (37 kJ/g) for fat. Alcohol is also technically considered a macronutrient and contains 7 kcal/g (29 kJ/g).

Withdrawing 4% or less of retirement savings each year has long been a popular rule of thumb for retirees. However, due to high inflation and market volatility, the rule is less reliable now. Retirees will need to decrease their spending and withdrawal rate to 3.3% so they don't run out of money.

Atwater. The USDA SR database, in contrast, commonly uses the Atwater method.

A minimum of 7000 calories equals a weight gain of 1 kg. So, if you consume 1000 calories more than your typical consumption, you would have gained 1 kilogram by the end of the week.

Hafthor Bjornsson, better known as 'The Mountain' from Game of Thrones, has revealed how he maintains his ultra-muscular physique — and it includes eating four steaks and 5lbs of rice per day.

When applied to mixed diets, Atwater factors consistently overestimate the ME content of the diet. In a study to compare the Atwater-determined energy value of a mixed diet consumed by older adults to the measured energy value, it was found that the Atwater factors overestimated the ME of the food by 26% (26).

The number of kcalories that 1 g of a nutrient yields when completely oxidized; the fuel factor is 4 for carbohydrate and protein, 9 for fat, and 7 for alcohol. Fuel factors are used in computing the energy values of foods and diets (e.g., 10 g of fat yields 90 kcal).

What is metabolizable energy? ›

Metabolizable energy is defined as the amount of energy available to the body from food after accounting for the obligatory energy losses, mostly in stool and urine. Most dietary energy comes from dietary fat, protein, and carbohydrate.

In short, the 4% rule just assumes you're going to spend the same amount after inflation every year, that you're going to have a fixed lifestyle. And it uses failure rates to evaluate investment choices. "It's not realistic," said Finke. "It's not efficient."
